Comments

Object coordinates updated according to AT-report 142824 of Group GaiaAlerts
Previous RA, DEC: 15:21:46.336, +30:43:15.80 (230.4430672, +30.7210555)
Updated RA, DEC: 15:21:46.340, +30:43:16.03 (230.443083, 30.721119)

The spectrum of SN2020dok obtained by the NUTS2 collaboration, in colllaboration with POISE, indicated this is a pre-maximum type Ia supernovae. Comparison with astrodash suggest it is a 1991T-like subtype around a week before maximum.
